flutter - Flutter carousel_slider 通过按钮单击更改图像数组

Question

我有 3 个按钮，每个按钮都有图像数组，我需要在单击按钮时更改轮播项目。现在我已经通过选项卡实现了它，但是它非常重地加载了应用程序，动画变得很慢，好像 FPS 下降了一样。只想使用一个滑块并在单击按钮时更改其内容。但是我没有在轮播API中找到它。

我的代码：

final List < String > imgList = [
    'assets/category/pubg.png',
    'assets/category/sparta.jpg',
    'assets/category/stormfall-age-of-war.jpg',
    'assets/category/warface.jpg',
    'assets/category/warface-logo.jpg',
    'assets/category/playstation.png'
];

final List < Widget > imageSliders = imgList
    .map((item) => Container(
        child: Container(
            //margin: EdgeInsets.symmetric(horizontal: 5),
            child: ClipRRect(
                borderRadius: BorderRadius.all(Radius.circular(30.0)),
                child: Stack(
                    children: < Widget > [
                        Image.asset(item, fit: BoxFit.cover, width: 1000.0),
                        Positioned(
                            bottom: 0.0,
                            left: 0.0,
                            right: 0.0,
                            child: Column(
                                mainAxisSize: MainAxisSize.max,
                                crossAxisAlignment: CrossAxisAlignment.stretch,
                                children: < Widget > [
                                    Container(
                                        decoration: BoxDecoration(color: Colors.white),
                                        padding: EdgeInsets.only(top: 10.0),
                                        child: Text(
                                            'Slide # ${imgList.indexOf(item)}',
                                            textAlign: TextAlign.center,
                                            style: TextStyle(
                                                color: const Color(0xFF4F4F4F),
                                                    fontSize: 16,

                                        ),
                                    ),
                                    Container(
                                        decoration: BoxDecoration(color: Colors.white),
                                        padding: EdgeInsets.only(bottom: 10.0),
                                        child: Text(

                                                    fontSize: 12,
                                            ),
                                        ),
                                    ),
                                ],
                            ),
                        ),
                    ],
                )),
        ),
    ))
    .toList();
